use,

application filed January 25, 1909.

To all whom it may concern:

Be it known that I, Evnnes'r A. Burns, a citizen of the United States, residing at Madera, in the county of Chihuahua, Mexico, have invented certain new and useful Improvements in Feeders for Tube-Mills; and 1 do hereby declare thE following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to tube mills and more especially to a feeder therefor.

With the presentmanner of feed'ng tube mills a complicated structure is necessary at the end of the mill in order to property attach the feeder, moreover, the present feed ers are all extremely liable to clog and the.

feed therefrom becomes uneven so that the mill is irregularly supplied with the sand.

The principal object of the present invention is to provide a feeder for tube mills which may be readily attached to any mill without niateria ly attesting thcconstructiou of the mill and which will be free from clog- Another obpsct of the invention is to prdvide' a feeder-for tube mills which will deliver a regular charge of sand to the mill upon every revolution thereof. Vi ith the above and other objects in view, the invention consists, in general, of a feed pipe of peculiar form in combination w'th a trough adapted to hold the material to be fed. to the mill.

The invention further consists in certain novel arrangements of parts hereinafter fully described, illustrated in the accom panying drawings and specifically'set forth in the claim.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a side elevation of a portion of a feed mill equipped with this invention. Fig. 2 is an end elevation thereof, a portion of the food trough be ing broken away to show the lower part of the feeder.

The numeral 10 indicates the end of a tube mill and in this instance is shown the end opposite the driving mechanism which is notdecmcd essential here to be shown as the same is that common to all tube mills.

thereof.

Specification of Letters Patent. Patented June "2', 1910.

Serial No. 474,086.

The tube mill 10 is provided with a hollow stub shaft ll which is'carried in bearings 12.

The feeder consists of a section of pipe,

preferably about three inches in diameter,-

which has its end threaded as indicated at 18 and is securely screwed into the hollow arranged that the end 18 of the spiral will pass through the trough at everyrevolution of the tube mill. This trough is supplied with the material to be fed to the mill in any desired manner.

lVhcn the mill is started the spiral revolves and at each revolution the end 18 dips into the material and takes up a charge ity, constantly remains at the lower portion of the spiral and follows the same around until the straight section of pipe is reached. At this point it turns and flows directly into the tulle mill. As soon as the end 18 has passed through the trough the remaining material flows in behind the end and is ready for the next charge to be picked up.

It will be observed that this device isabsolutely free from all valves, pistons and other complicated apparatus liable to wear and become clogged. It will further be observed that, even if this device does become slightly clogged by some of the sand sticl ing to the sides when the mill is at rest, the action of the inflowing sand will automatically clean the sameout.

As can be seen this device is of great simplicity and low cost of manufacture and by actual experiment it has been found. that it requires a minimum of repairs.

There has thus been provided a simple and clficient device of the character described and. for the purpose specified.

Having thus described the invention, what is claimed as new, is

In combination with. a tube mill, a hollow stub shaft supporting the some and a feeder comprising a pipe of uni l'uri: sectional Situated below the plane of revolution of this spiral is a trough 17 so This charge, by the action of gravarea throughout its length and having a shot section extenlding 1n (izligement I:vith ture, in presenceof two witnesses,
